私はopenjpaに問題があり、intellij idea 12でファイルを自動的に生成しました「persitence.xml」とJavaオブジェクトは、データベースのモデルに基づいて、PaginaController.javaとPaginaDao.javaを作成しますが、生成されたEntityMaganerFactoryを作成します。
PaginaDAO.java、ここでアプリケーションがクラッシュします。
package cl.im.ciclos.Dao;
import cl.im.ciclos.model.Pagina;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public class PaginaDao {
static EntityManagerFactory factory;
static EntityManager em;
public PaginaDao(){
factory = Persistence.createEntityManagerFactory("sistemaPU");
em = factory.createEntityManager(); //==>this line generates the exception.
}
public void savePagina(String nombre, String file){
em.getTransaction().begin();
Pagina pagina = new Pagina();
pagina.setNombre(nombre);
pagina.setNombreArchivo(file);
em.persist(pagina);
em.getTransaction().commit();
}
}
